MACHNE FOR SETTING LACING-HOOKS.

Be it known that I, WILLIAM H. KINGS- I TON, of Newark, in the county of Essexand State of New Jersey, have invented certain new and useful Improvements in Machines for Setting Lacing-Hooks, of which the folv'lowing is a speciiication.

v This invention has for its object to provide la simple and effective machine for setting A2--2 of Fig. 1.

lacing hooks; and it consists in the severa improvements which I will now proceed to describe and claim.

Ofthe accompanying drawings, forming a part of this`V s eciication,-Figure 1 represents a side e evation'of my improved machine. Fig. 2 rpresents a section on line ig. 3 represents a side view of a portion of the chute and the let-off device therein. Fig. 4 represents a top view of the machine. Fig. 5 re )resents a perspective view of the device, which separates hooks from the mass in the reservoir, and delivers them to the chute. Fig. 6 represents a front elevationof portions of the chute. Fig. 7 represents a front elevation of the machine. Fig. 8 represents a section on line 8--8 of Fig. 7. Fig. 9 represents a section on line 9--9 of Fig. 4. Fi 1() represents a section on line 10-10 of ig. 7. Fig. 11 represents a section on line'11-11 of Fig. 4. Fig. 12 represents a section similar to Fig. 8, with the anvil and carrier in elevated position.

The same letters of reference indicate the I same parts in all -thejigures In the drawings, a represents the supporting frame of the machine, which is provided with an inclined chute comprising an upper section b and a lower section b. The section l) is formed in cross-section as shown in Fig. 2, and has the side-plates c c2 separated by the longitudinal slot or. passage which receives the neck of a lacing-hook c. The head 4 of the hook stands within the plate c2, and the shank or eyelet-2 stands outside. At the upper end of the cection is located a ,hook-reservoir' having a separator for delivering lacing-hooks to the chute in the position shown in Fig. 2.. Said separator is an oscillating segmental plate d attached at its lends to arms d d2, which are aili'xed to a rocksliaft d3. Said rock-shaft is mounted to oscillate in bearingsformed in heads e e affixed to the frame of the machine and forming the ends of the reservoir, which has la 'segmental 'body e between said heads.

REISSUED lThe Asaid body issubstantially parallel with the separator-plate d, as shown in Fig. 11.

Thezheads e e and the segmental body e constitute the iixed parts of the reservoir in which the separator-plate d oscillates, said reservoir being completed by a movable gate e2 pivotally connected' by studs or pivots e3 e3 with the heads e e. The gate e2 is provided with arms e4 e4, one of which is engaged by the spring-pressed locking-pin e5 lvbvhcich holds the gatecnormally in the tposition shown in Fig. 11, so that it forms a wall coperating with the fixed parts e e and "e' in holding a mass of lacing-hooks above said separator-plate. The gate e2 can be displaced, A

as shown by dotted lines in Fig. 11, .by withdrawing the locking-pin e5 to permit the quick removal of the lacing-hooks in the reservoir when it is desired to change from one style of hooks to another. One of the xedheads e is provided with an orifice e which coincides with the upper end of the plate vc2, so that a lacing-hook passing outwardly from the reservoir through the oriiicle e. in the position shown iii Fig. 2 will engage the plate c?, as shown in said ligure. One edge d* of the separator d, which I term the hook-delivering edge, is inclined relatively to the axis or shaft d3, as shown in Fig. 4, and said inclined edge is arranged so that when the separator is at one extreme of its oscillating movement, its` lower. end will coincide with the upper end'of the plate c2, as shown bydotted lines in Fig. 1. The inclination of the hook-deliverin edge d4 is such that any lacing-hooks that cstride it iii the position shown in Fig. 11 will slide from it onto the upper end of the plate c2 when the edge d* coincides with said plate. The separator d is located.in such close proximity to the se mental body e of the reservoir, that only t ie head ortions of the lacing-hooks can be inserte in the space between the separator and the reservoir body consequently when the separator is oscillated,

the lacing-hooks can only bestride this edge l slide olf from the inclined edge d4 `onto the plate c2, and will therefore slide down the In Fig. 11 the position of the separator at one extremity of its oscillations is indicated by' solid lines, this position, being that in which its front or inclined edge is in position.

to discharge the hooks onto the plate c2. In

said ligure the position of' the separator when at the other or rear extremity of lits oscillations, is indicatedbydotted lines. It will also be seen by reference to said gure, that the distance between the front and rear edges of the separator is greater than the distance between'its extremes of oscillation and therefore neither edge can have a Adownward movement among the mass of hooks in the reservoir, which downward 4movement might have a tendency to damage the hooks or the edge of the separator.. `In other words, although the separator is an oscillating one, neither edge has a movement among the hooks that might cause damage'. It will readily be understood furthermore, that if any hooks become caught on the de-y livering edge and fail to slide therefrom onto the plate c2, they will -be dislodged by the.

next backward movement of the delivering edge among the hooks in the reservoir. l

The section b of the chute is Given' a uarter-turn at its lower end, and Afiliere delivers the hooks supplied to it, to the section b, which comprises two curved plates 6 6, which are horizontal in their cross-section and are separated by a slot 7 of sufficient width to receive the neck 3 of the lacing-hook, the section b having a passage 8 under. the anges 6, of suitable width to receive the outer portion or head of a lacing-hook. The section b delivers the hooks vin the position shown in Fig. 1,'the hooks being given this position by ytheir passage from the section b to thesectinv b. A transferring device is located at the lower portion of the section b, to transfer lacing-hooks, one at a time, to the section b. Said. transferring device comprises a plate g pivoted at g and having an arm gZ which is engaged by a reciprocating slide h hereinafter referred to. The plate g has a recess g3 formed to receive the head of the lowest lacing-hook in the section b when the plate g is in the position shown in Fig. 1. When said plate is moved to the osition shown in Fig. 3, it forces the hook into the section c.

The curvature of the section t is suchthat ravitation is not sufficient to carry the ooks-LA to the lower end of said chute, the

hooks stopping before they reach said lower end. The slide 7i. is lprovided'with a projecting arm or ejector h which enters the lower portions of the section b and ejects therefrom each hook that is deposited therein by the action of the let-off device g.. The ejecchine.

-tor 71, .forcs each hook forward onto an anvil j, which ismounted upon a vertically movable carrier k sliding in a fixed guide 7c attaphed to the frame of the machine, the said Vof the frame. a.

The anvil-carrier 7c is reciprocated ver/tically ln-the guide or casing 7c by means of a lever 'n pivoted at o to theframe of the ma- One arm of said lever (the shorter) enters a slotur2 in the carrier k. T he other and longer arm of the lever has4 a slot n, which receives a block p pivoted eccentrically to a disk g on a shaft 1. The rotation ofsaid shaf/t oscillates the lever 'n and causes it to reciprocate the carrier c.

l The anvil j is secured by screws j to a holder f2, which is pivoted at ja to the carrier 7c and is adapted to swing outwardly from the carrier, with the anvil, to withdraw the anvil from each lacing-hook after it has been attached. The holder i2 is normally held in the position shown in Figs. l and 8, by a spring 7'4 acting on a stud y which bears on t 1e holder, and is displaced against the pressure-of said spring after each ascent of the carrier, by means of a catch pivoted at j to the frame of the machine and adapted to yield upwardly against the stress of a s ring j?, but held, rigidly by a stop-shoul er js against downward movement from the position shown in Fig. -81 This lateral movement oflthe anvil toilvovard and flromthe source of supp y, a s ring eing emp oye to 'yieldingly hold salfd anvil toward the. chuteor saidl source of sup ly, possesses the further .advantage of avoi ing accidents in the event of a hook being fed by the ejector 7L which hook does not lhave an opening large enough to enable it to be fully forced onto said anvil. If such a hook, with -an unduly contracted opening were to be forced partially onto the anvil by the ejector, and stick there, the said anvil will yield laterally away from the source of supply under the` pressure exerted by 'said ejector, so that the defective hook will be fully cleared from ,the lower end of the slot in the chute-section b', before the anvil holder is moved upwardly. When the carrier 7c rises, a lug jg on the anvil-holder j2 strikes the catchvji", which yields upwardly until the lug passes `above it, and then springs back under the lug. When the carrier 7c descends, the catch standing in the ath of the lug jg forces the latter, with the liolder jzand anvilj, outwardly, thusremoving the anvil from the hook last attached, so that the work can be readily moved along re aratory to the attachment of another cork. The anvil is adapted to slide or yield vertically to a slight extent on its holder f', bymeans of slots j through which the screws e tubular shank 2 of each j" pass, and a spring jf which normally holds theanvil slightly above the upper end of the holder. A stop acts as an abutmentY for the lower end of the anvil when the latter is in the position shown in Fig. 8, to. pre.

i vent said anvil from being oscillated on the during the setting operation.

pivot ja when the ejector h is forcing a hook on to the anvil. Said stop also serves to raise the anvil relatively to the carrier 7c so as to leave a space between the underside of the toe of the an-vil and the top of the clamp T, presently described, so that said clamp will .not interfere with the placing of the hook on vice g and ejector 7i is rejected or moved to the position shown in ig. l, by means of a sliding arm s arranged .to be moved by an eccentric pin s on the diskg, .and is retracted by a spring s2 after the pin s releases the arm s. The slide h is yieldinglyconnected to the arm s through an interposed spring s3, so that the ejector 71, is adapted 4to yield in case a hook becomes caught or wedged in i the chute,` damage to the hook, chute, and

ejeietor being thus prevented. The separator d is oscillated by means of a crank-arm .t affixed to the shaft d, and a rod t connecting said arm with thelever n.

Operation- The hook-separator d is oseillated as described, -and delivers to the l chute the hooks that'collect on its inclined edge d. The hooks accumulate-in the section b of the chute,` and are transferred, one at altime, to the section b" by the oscillating plate g. 'The liberated hook slides down the section b While the ejector is being retracted, said hook being delivered in front of the ejector, and is moved forward by the ejector when the latter is again projected. The carrier lc and anvil y' are depressed when the ejector is projected, so thattheejector forces the hook onto the anvil, as shown in Fig. 1. The ejector is' retracted by the spring s2, before the carrier 7c and anvil j rise topresent the hook to the setting-die. The anvil is4 raised after the retraction of the ejector, and isswung outwardly by the catch f5, justas it begins to descend.

The described mechanism is timed so that i each complete rotation of theshaft q first projects the ejector, then raises the anvil (the ejlector` being released and retracted before t le anvil rises), and then depresses the, anvil.

An automatic stop motion is provided, which arrests'the motion of the shaft after each complete rotation, while the anvil is depressed and the ejector retracted. Said stop-motion may be of any suitable construction, and is preferably constructed as shown in Figs. 9 and 10, in which I show a latch z pivoted at z to the shaft q and normally thrown outward by a s ring z2 to engage shoulders 212 in the hu of a gearsB which is loose on the shaft g and meshes with a gear 24 (see Fig. 4) affixed to the driving-shaft e7 represents a cam-shaped stop, which is aflixed to a rock-shaf t es having a crank-arm e connected by a rod 21 with a treadle (not shown). The stop 27 stands' normally in the path of the latch z, as shown in Figs. 7 and 10, and when it enters said path its cam portion 213 swings the latch inwardly, out of engagement with the shoulder in the gear a? and its stop' portion .214 arrests said latch and with it the shaft. When the'stop is moved out of the path-of the latch, as shown in Fig. 9, by the depression of the treadle, the latch engages one of the shoulders e, and thus engages the shaft tating gear z3.
